Okay so basically I have a calendar display and when you click on anyone of the dates on it, it creates a new panel with a label displaying the date selected. I also made it so when you click on a date and a new panel is made, a label, textbox and button is created and placed onto that new panel as well.
So what I want and have been struggling with is for me to enter something into that textbox then to press the button to submit it and then for it to show on the label.
I think I know what the issue is but I've been stuck at this for hours.
Here is my code:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void monthCalendar1_DateSelected_1(object sender, DateRangeEventArgs e)
{
Panel newPanel = new Panel();
this.Controls.Add(newPanel);
newPanel.Visible = true;
newPanel.Size = new Size(564, 831);
newPanel.Location = new Point(0, 190);
newPanel.BringToFront();
Label textLabel = new Label();
textLabel.Size = new Size(500, 500);
textLabel.Font = new Font(textLabel.Font.Name, 25, textLabel.Font.Style);
textLabel.Location = new Point(3, 3);
Label dateLabel = new Label();
dateLabel.Size = new Size(500, 500);
dateLabel.Font = new Font(dateLabel.Font.Name, 25, dateLabel.Font.Style);
dateLabel.Location = new Point(128, 3);
Button Submitbutton = new Button();
Submitbutton.Location = new Point(100, 500);
Submitbutton.Text = "Add Food";
Submitbutton.Size = new Size(400, 100);
Submitbutton.BackColor = Color.Aqua;
Submitbutton.BringToFront();
Submitbutton.Click += Button_Click;
TextBox textBox = new TextBox();
textBox.Location = new Point(100, 650);
textBox.Size = new Size(500, 500);
textBox.BackColor = Color.Aqua;
textBox.Visible = true;
textBox.Text = "Enter food here...";
textBox.BringToFront();
Label inputtedFood = new Label();
inputtedFood.Size = new Size(500, 500);
inputtedFood.Font = new Font(inputtedFood.Font.Name, 25, inputtedFood.Font.Style);
inputtedFood.Location = new Point(100, 600);
inputtedFood.Text = "placeholder";
newPanel.Controls.Add(dateLabel);
newPanel.Controls.Add(textLabel);
newPanel.Controls.Add(Submitbutton);
newPanel.Controls.Add(textBox);
newPanel.Controls.Add(inputtedFood);
String myCalendar = monthCalendar1.SelectionRange.Start.ToShortDateString();
textLabel.Text = "Date:";
dateLabel.Text = myCalendar;
}
private void Button_Click(object sender, EventArgs e)
{
inputtedFood.Text = textBox.Text;
}
private void monthCalendar1_DateChanged_1(object sender, DateRangeEventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
}
}
I tried the above code and was met with errors that are shown in the post.
Totally agree with both LarsTech and Ňɏssa Pøngjǣrdenlarp, you should be building a UserControl in place of the Panel and placing the TextBox, Button, and Label inside of that.
Your immediate question, though:
So what I want and have been struggling with is for me to enter
something into that textbox then to press the button to submit it and
then for it to show on the label.
Can be accomplished with this simple code:
Button Submitbutton = new Button();
// ... more code ...
Submitbutton.Click += (s2, e2) =>
{
inputtedFood.Text = textBox.Text;
};
Here's a little example showing it in action:
private void button1_Click(object sender, EventArgs e)
{
FlowLayoutPanel flp = new FlowLayoutPanel();
TextBox textBox = new TextBox();
// ... more code ...
Label inputtedFood = new Label();
inputtedFood.Text = "placeholder";
// ... more code ...
Button Submitbutton = new Button();
// ... more code ...
Submitbutton.Click += (s2, e2) =>
{
inputtedFood.Text = textBox.Text;
};
flp.Controls.Add(textBox);
flp.Controls.Add(Submitbutton);
flp.Controls.Add(inputtedFood);
flowLayoutPanel1.Controls.Add(flp);
}
The output:
I have a Form which has a TextBox and a Button. I have set the Form's AcceptButton property to my Button, and set the TextBox's AcceptsReturn property to false:
class Window : Form
{
private TextBox textBox1;
private Button btn;
public Window()
{
this.Size = new Size(200, 200);
this.AcceptButton = this.btn;
textBox1 = new TextBox();
textBox1.Location = new Point(10, 10);
textBox1.Width = 50;
textBox1.AcceptsReturn = false;
this.Controls.Add(textBox1);
btn = new Button();
btn.Text = "Test";
btn.Location = new Point(textBox1.Right + 10, 10);
btn.Click += btn_Click;
this.Controls.Add(btn);
}
void btn_Click(object sender, EventArgs e)
{
MessageBox.Show("Works");
}
}
class Program
{
static void Main(string[] args)
{
Application.EnableVisualStyles();
Application.Run(new Window());
}
}
However, when pressing the Enter key while the TextBox has focus, the AcceptButton of the Form is not activated. I worked around it using the KeyDown event of the TextBox like so:
textBox1.KeyDown += (s,e) => { if (e.KeyCode == Keys.Enter) btn.PerformClick(); } ;
And although it works I am curious as to why the earlier method using the AcceptButton property failed.
The problem is that you set the Form's AcceptButton to btn before you instantiate it. Move this.AcceptButton = this.btn; to any line AFTER btn = new Button();.. btn is pointing to a null reference up until new Button(). Once you instantiate btn you can use it to set AcceptButton.
You just wrote one line in the wrong place.That's the answer:
public Form1()
{
InitializeComponent();
this.Size = new Size(200, 200);
textBox1 = new TextBox();
textBox1.Location = new Point(10, 10);
textBox1.Width = 50;
textBox1.AcceptsReturn = true;
this.Controls.Add(textBox1);
btn = new Button();
btn.Text = "Test";
btn.Location = new Point(textBox1.Right + 10, 10);
btn.Click += btn_Click;
this.Controls.Add(btn);
this.AcceptButton = this.btn;
}
I hope this helps you!
I am trying to show a WinForm (inputbox) from a console application in C# and wait until the user closes the form. It is important for me to have the inputbox ontop and active when it opens. ShowDialog() is not working in my case as in some cases it does not appears as an active form. So I'd like to change my code and use Show(). This way I can manually make find out if the form is active or not and if not activate it myself. With ShowDialog(). my code stops and I can not do anything until the from is closed.
Below is my code. It does show the inputbox, however it is frozen. What am I doing wrong please? As clear the while-loop after "inputBox.Show();" is not doing anything, but if I can manage to run the loop and the inputbox does not freeze, I will sort out the rest myself. I appreciate your help.
public static string mInputBox(string strPrompt, string strTitle, string strDefaultResponse)
{
string strResponse = null;
Form inputBox = new Form();
inputBox.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedToolWindow;
inputBox.ClientSize = new Size(500, 85);
inputBox.Text = strTitle;
inputBox.StartPosition = System.Windows.Forms.FormStartPosition.Manual;
inputBox.Left = (Screen.PrimaryScreen.Bounds.Size.Width / 2) - (inputBox.ClientSize.Width / 2);
inputBox.Top = (Screen.PrimaryScreen.Bounds.Size.Height / 2) - (inputBox.ClientSize.Height / 2);
Label lblPrompt = new Label();
lblPrompt.Text = strPrompt;
inputBox.Controls.Add(lblPrompt);
TextBox textBox = new TextBox();
textBox.Text = strDefaultResponse;
inputBox.Controls.Add(textBox);
Button okButton = new Button();
okButton.Text = "&OK";
inputBox.Controls.Add(okButton);
Button cancelButton = new Button();
cancelButton.Text = "&Cancel";
inputBox.Controls.Add(cancelButton);
okButton.Click += (sender, e) =>
{
strResponse = textBox.Text;
inputBox.Close();
};
cancelButton.Click += (sender, e) =>
{
inputBox.Close();
};
inputBox.AcceptButton = okButton;
inputBox.CancelButton = cancelButton;
SetWindowPos(inputBox.Handle, HWND_TOPMOST, inputBox.Left, inputBox.Top, inputBox.Width, inputBox.Height, NOACTIVATE);
inputBox.Show();
while {true}
Thread.Sleep(100);
Application.DoEvents();
return strResponse;
}
I'm not sure why you are taking this route, I'm sure there are better ways to do it (explain one at the end). however to make your code run you should add Application.DoEvents() inside your loop
the code should be something like this:
var formActive = true;
inputBox.FormClosed += (s, e) => formActive = false;
inputBox.Show();
inputBox.TopMost = true;
inputBox.Activate();
while (formActive)
{
Thread.Sleep(10);
Application.DoEvents();
}
and the whole method will be:
public static string mInputBox(string strPrompt, string strTitle, string strDefaultResponse)
{
string strResponse = null;
Form inputBox = new Form();
inputBox.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedToolWindow;
inputBox.ClientSize = new Size(500, 85);
inputBox.Text = strTitle;
inputBox.StartPosition = System.Windows.Forms.FormStartPosition.Manual;
inputBox.Left = (Screen.PrimaryScreen.Bounds.Size.Width/2) - (inputBox.ClientSize.Width/2);
inputBox.Top = (Screen.PrimaryScreen.Bounds.Size.Height/2) - (inputBox.ClientSize.Height/2);
Label lblPrompt = new Label();
lblPrompt.Text = strPrompt;
inputBox.Controls.Add(lblPrompt);
TextBox textBox = new TextBox();
textBox.Text = strDefaultResponse;
inputBox.Controls.Add(textBox);
Button okButton = new Button();
okButton.Text = "&OK";
inputBox.Controls.Add(okButton);
Button cancelButton = new Button();
cancelButton.Text = "&Cancel";
inputBox.Controls.Add(cancelButton);
okButton.Click += (sender, e) =>
{
strResponse = textBox.Text;
inputBox.Close();
};
cancelButton.Click += (sender, e) =>
{
inputBox.Close();
};
inputBox.AcceptButton = okButton;
inputBox.CancelButton = cancelButton;
var formActive = true;
inputBox.FormClosed += (s, e) => formActive = false;
inputBox.Show();
inputBox.TopMost = true;
inputBox.Activate();
while (formActive)
{
Thread.Sleep(10);
Application.DoEvents();
}
return strResponse;
}
but I think it would be a better Idea to Derive from Form and create a InputBox and set TopMost and call Activate OnLoad to create what you need, then simply call ShowDialog, something like:
class Inputbox : Form
{
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
TopMost = true;
Activate();
}
}
and better to put UI code in InputBox class as the whole code and usage would be like:
class Inputbox : Form
{
public string Response { get; set; }
public Inputbox(string strTitle, string strPrompt, string strDefaultResponse)
{
//add UI and Controls here
FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedToolWindow;
ClientSize = new Size(500, 85);
Text = strTitle;
StartPosition = System.Windows.Forms.FormStartPosition.Manual;
Left = (Screen.PrimaryScreen.Bounds.Size.Width/2) - (ClientSize.Width/2);
Top = (Screen.PrimaryScreen.Bounds.Size.Height/2) - (ClientSize.Height/2);
Label lblPrompt = new Label();
lblPrompt.Text = strPrompt;
Controls.Add(lblPrompt);
TextBox textBox = new TextBox();
textBox.Text = strDefaultResponse;
Controls.Add(textBox);
Button okButton = new Button();
okButton.Text = "&OK";
Controls.Add(okButton);
Button cancelButton = new Button();
cancelButton.Text = "&Cancel";
Controls.Add(cancelButton);
okButton.Click += (sender, e) =>
{
Response = textBox.Text;
Close();
};
cancelButton.Click += (sender, e) =>
{
Close();
};
AcceptButton = okButton;
CancelButton = cancelButton;
}
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
TopMost = true;
Activate();
}
}
public static string mInputBox(string strPrompt, string strTitle, string strDefaultResponse)
{
string strResponse = null;
Inputbox inputBox = new Inputbox(strPrompt,strTitle,strDefaultResponse);
inputBox.ShowDialog();
return inputBox.Response;
}
You need to run a message loop:
Application.Run(inputBox);
It says createPassword and repeatPassword are not in the current context. Why and what happens ?
Code;
public MainPage()
{
InitializeComponent();
TextBox createPassword = new TextBox();
createPassword.Width = 400;
TextBox repeatPassword = new TextBox();
repeatPassword.Width = 400;
Button createButton = new Button();
createButton.Content = "Create New Password";
createButton.Click += new RoutedEventHandler(savePassword);
StackPanel content = new StackPanel();
content.HorizontalAlignment = HorizontalAlignment.Center;
content.Children.Add(createPassword);
content.Children.Add(repeatPassword);
content.Children.Add(createButton);
LayoutRoot.Children.Add(content);
}
void savePassword(object sender, RoutedEventArgs e)
{
string password1 = createPassword.Text;
string password2 = repeatPassword.Text;
}
createPassword and repeatPassword must be class members to use them in different class methods:
TextBox createPassword;
TextBox repeatPassword;
public MainPage()
{
InitializeComponent();
createPassword = new TextBox();
createPassword.Width = 400;
repeatPassword = new TextBox();
repeatPassword.Width = 400;
Button createButton = new Button();
createButton.Content = "Create New Password";
createButton.Click += new RoutedEventHandler(savePassword);
StackPanel content = new StackPanel();
content.HorizontalAlignment = HorizontalAlignment.Center;
content.Children.Add(createPassword);
content.Children.Add(repeatPassword);
content.Children.Add(createButton);
LayoutRoot.Children.Add(content);
}
void savePassword(object sender, RoutedEventArgs e)
{
string password1 = createPassword.Text;
string password2 = repeatPassword.Text;
}
I am trying to mimic the behavior of, for example, Windows Explorer and how the Favorites items can launch a context menu.
I currently am using:
contextMenu.Show((sender as ToolStripMenuItem).GetCurrentParent().PointToScreen(e.Location));
This occurs in the MouseDown event of the ToolStripMenuItem. The problem is that the menu closes immediately after right-click, and I don't know any way to suspend it while the context menu is open.
I've tried deriving from ToolStripMenuItem and overriding the MouseDown/MouseUp but I can't figure out how to keep it open on click.
Is there a good way of doing this?
This is what I've had luck with, it's a bit more direct:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
void MenuItemContext(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left) return;
ToolStripMenuItem mID = (ToolStripMenuItem)sender;
ContextMenu tsmiContext = new ContextMenu();
MenuItem Item1 = new MenuItem();
MenuItem Item2 = new MenuItem();
Item1.Text = "Item1";
Item2.Text = "Item2";
tsmiContext.MenuItems.Add(Item1);
tsmiContext.MenuItems.Add(Item2);
Item1.Click += new EventHandler(Item1_Click);
Item2.Click += new EventHandler(Item2_Click);
hndPass = mID.Text;
tsmiContext.Show(menuStrip1, menuStrip1.PointToClient(new Point(Cursor.Position.X, Cursor.Position.Y)));
}
private String hndPass;
void Item1_Click(object sender, EventArgs e)
{
MenuItem mID = (MenuItem)sender;
MessageBox.Show("You clicked " + mID.Text + " in the context menu of " + hndPass);
}
void Item2_Click(object sender, EventArgs e)
{
MenuItem mID = (MenuItem)sender;
MessageBox.Show("You clicked " + mID.Text + " in the context menu of " + hndPass); ;
}
}
One way that you could accomplish this is by using the ToolStripDropDown control to host a ListBox inside of the ToolStripDropDown.
This may require some tweaking regarding the AutoClose behavior, but it should get you started:
First in your main form, add the following line to your ToolStripDropDropDown item
toolStripDropDownButton1.DropDown = new CustomListDropDown();
Then create a custom drop down class as follows:
public class CustomListDropDown : ToolStripDropDown
{
private ContextMenuStrip contextMenuStrip1;
private ToolStripMenuItem toolStripMenuItem1;
private ToolStripMenuItem toolStripMenuItem2;
private ToolStripMenuItem toolStripMenuItem3;
private System.ComponentModel.IContainer components;
public ListBox ListBox { get; private set; }
public CustomListDropDown()
{
InitializeComponent();
this.ListBox = new ListBox() { Width = 200, Height = 600 };
this.Items.Add(new ToolStripControlHost(this.ListBox));
this.ListBox.ContextMenuStrip = contextMenuStrip1;
this.ListBox.MouseDown += new MouseEventHandler(ListBox_MouseDown);
contextMenuStrip1.Closing += new ToolStripDropDownClosingEventHandler(contextMenuStrip1_Closing);
//add sample items
this.ListBox.Items.Add("Item1");
this.ListBox.Items.Add("Item2");
this.ListBox.Items.Add("Item3");
this.ListBox.Items.Add("Item4");
}
void contextMenuStrip1_Closing(object sender, ToolStripDropDownClosingEventArgs e)
{
this.Close();
this.AutoClose = true;
}
void ListBox_MouseDown(object sender, MouseEventArgs e)
{
this.AutoClose = false;
this.ListBox.SelectedIndex = this.ListBox.IndexFromPoint(e.Location);
}
private void InitializeComponent()
{
this.components = new System.ComponentModel.Container();
this.contextMenuStrip1 = new System.Windows.Forms.ContextMenuStrip(this.components);
this.toolStripMenuItem1 = new System.Windows.Forms.ToolStripMenuItem();
this.toolStripMenuItem2 = new System.Windows.Forms.ToolStripMenuItem();
this.toolStripMenuItem3 = new System.Windows.Forms.ToolStripMenuItem();
this.contextMenuStrip1.SuspendLayout();
this.SuspendLayout();
//
// contextMenuStrip1
//
this.contextMenuStrip1.Items.AddRange(new System.Windows.Forms.ToolStripItem[] {
this.toolStripMenuItem1,
this.toolStripMenuItem2,
this.toolStripMenuItem3});
this.contextMenuStrip1.Name = "contextMenuStrip1";
//
// contextMenuStrip1.ContextMenuStrip
//
this.contextMenuStrip1.Size = new System.Drawing.Size(181, 48);
//
// toolStripMenuItem1
//
this.toolStripMenuItem1.Name = "toolStripMenuItem1";
this.toolStripMenuItem1.Size = new System.Drawing.Size(180, 22);
this.toolStripMenuItem1.Text = "toolStripMenuItem1";
//
// toolStripMenuItem2
//
this.toolStripMenuItem2.Name = "toolStripMenuItem2";
this.toolStripMenuItem2.Size = new System.Drawing.Size(180, 22);
this.toolStripMenuItem2.Text = "toolStripMenuItem2";
//
// toolStripMenuItem3
//
this.toolStripMenuItem3.Name = "toolStripMenuItem3";
this.toolStripMenuItem3.Size = new System.Drawing.Size(180, 22);
this.toolStripMenuItem3.Text = "toolStripMenuItem3";
//
// CustomListDropDown
//
this.Size = new System.Drawing.Size(2, 4);
this.contextMenuStrip1.ResumeLayout(false);
this.ResumeLayout(false);
}
}
In my tests this worked reasonably well. Let me know how it goes.
As ContextMenuStrip is derived from ToolStripDropDown, you could do this:
private ContextMenuStrip CopyToContextMenu(ToolStripMenuItem mnuItemSource)
{
var mnuContextDestination = new ContextMenuStrip();
//Move itens from ToolStripMenuItem to ContextMenuStrip
while (mnuItemSource.DropDown.Items.Count > 0)
{
mnuContextDestination.Items.Add(mnuItemSource.DropDown.Items[0]);
}
//Put ContextMenuStrip in ToolStripMenuItem using DropDown property
mnuItemSource.DropDown = mnuContextDestination;
return mnuContextDestination;
}
